| Portescap has expanded its family of
brush DC motors by introducing the 35GLT motors.
These RoHS-compliant motors have a 35mm
housing and weigh just 360 grams, while delivering a 40% increase in
torque-to-volume ratio when compared with standard iron core motors of
similar frame size.
The maximum continuous torque approaches
150 mNm in the 35GLT, a 25% improvement over similar conventional models.
They are available with five winding types in the voltage range of 24V to
90V, and are cost-effectively these motors can be customised for use with
a range of gearboxes and encoders.
“The 35GLT comes out of Portescap’s
history of innovation and experience in designing multi-layer coil Brush
DC coreless motors, and is precision engineered to minimize speed
variations at higher loads. As an example, the 48V coil has only 0.4%
speed variation when the motor has a load fluctuation of 5 mNm at a
continuous torque of 100 mNm.
In medical, aerospace and electronics
assembly markets, this unique design feature, for the 35GLT, improves
actuation at higher torques.
The higher continuous torque and output
power, in a compact lighter weight frame, reduces operator fatigue, which
is vital in applications such as power hand tools.
The 35GLT motors are well suited for use
in food processing, door automation, feed and assembly tool, seat
automation, missile actuation and hospital bed applications, among other
applications where high continuous torque is a requirement.
For highly demanding applications such as lab
automation, in which heat management is a prerequisite, the 35GLT motors
not only have less ambient heat dissipation (measured by Joule loss) than
comparable motors, but they can also be customised with a proprietary
fiber wrap insulation to further minimize heat dissipation. |
